| FSC certification | Confirm that the supplier’s FSC certificate is valid and that its scope covers the relevant paper products and activities. | Check the certificate code and certificate holder in the FSC public certificate database. Request the current certificate and confirm the exact product claim and transaction documents. | FSC claims should be supported by valid chain-of-custody documentation and used in accordance with FSC requirements. | A supplier offers an FSC logo or claim but cannot provide a verifiable certificate code or supporting sales documentation. |
| Paper specification | Agree on paper grade, basis weight, finish, color, recycled content, and whether the paper is coated or uncoated. | Request a written specification and check the paper label or supplier documentation against the approved sample. | Use an agreed specification with measurable details; “kraft paper” alone is not a complete material specification. | Material descriptions are vague, or the production paper differs from the approved specification. |
| Sample quality | Inspect dimensions, gusset formation, handle attachment, print alignment, color, seams, and overall finish. | Approve a pre-production sample and record its dimensions, artwork version, material, and any agreed tolerances. | Test the sample with the intended contents and carrying conditions before approving bulk production. | Only digital mock-ups are offered when a physical sample is needed to assess construction and materials. |
| Load performance | Check that the bag and handles suit the product’s weight, shape, and expected carrying time. | Conduct a repeatable load test using the intended contents; record the load, duration, and any tearing or handle failure. | Set the acceptance criteria with the supplier before sampling, since performance depends on paper, construction, and handle design. | Load capability is stated without a test method or without considering the actual contents. |
| Printing and artwork | Confirm print process, color references, artwork dimensions, bleed, and whether proofs are required. | Approve a final proof and verify that the printed sample matches the approved artwork and color expectations. | Allow time for artwork checks and proof approval before the production schedule begins. | Production is scheduled before artwork, colors, or proof requirements are finalized. |
| Sample lead time | Ask when the sample clock starts and whether it includes artwork preparation, material sourcing, and shipping. | Request a dated sample plan with separate preparation and delivery estimates. | Sample timing varies by customization, material availability, and shipping method; confirm the estimate in writing. | A single delivery date is promised without clarifying approval steps or shipping time. |
| Production lead time | Confirm the production start trigger, planned quantity, inspection stage, and expected completion date. | Request a schedule that distinguishes production time from sample approval, material procurement, and transit. | Lead times are order-specific. Reconfirm them after specifications, artwork, quantity, and sample approval are fixed. | The quoted lead time excludes material sourcing or begins before required approvals are complete. |
| Quality control | Agree on inspection points for dimensions, printing, bonding, handles, and packaging. | Use a written inspection checklist and request dated inspection photos or a pre-shipment inspection report. | Define defect categories and acceptance criteria before production rather than after goods are made. | Quality assurance is described only as a final visual check with no recorded criteria. |
| Shipping and order terms | Clarify carton quantities, packing method, shipping terms, destination, and who handles export documentation. | Request a written quotation that separates product, tooling or setup, packing, and freight where applicable. | Compare quotations using the same specifications, quantity, destination, and delivery terms. | Quotes omit key costs or use different specifications, making direct price comparison unreliable. |
| Supplier decision | Compare suppliers on traceable materials, sample results, documented quality controls, communication, and schedule clarity. | Use the same request-for-quotation checklist and sample criteria for each candidate. | Choose based on verified documentation and approved samples, not price or certification claims alone. | A decision is based solely on a low unit price or an unverified sustainability statement. |
